Doom

The Intel Core i5-14600K paired with the NVIDIA GeForce RTX 3080 delivers a decisive performance profile for Doom, with measured frame rates that consistently exceed the 60 FPS playability threshold across every tested resolution and settings combination. The data shows a system that is not merely capable, but one that provides substantial headroom at 1080p and 1440p, while remaining comfortably playable at 4K with Ultra settings. This analysis breaks down the measured FPS across resolutions, examines the division of labor between CPU and GPU, and contextualizes the combo’s standing among thousands of tested configurations.

Measured FPS Breakdown

The measured FPS data for this combination is comprehensive, covering three resolutions and four quality presets, with average frame rates recorded for each. At 1920x1080, the combo produces exceptional frame rates that will satisfy high-refresh-rate displays. With Low settings, the average FPS reaches 303.5, providing an extraordinarily smooth experience. Stepping up to Medium settings yields 259.4 average FPS, while High settings delivers 220.3 average FPS. The most demanding preset at this resolution, Ultra, still maintains an impressive 179.4 average FPS. These numbers indicate that at 1080p, the system is largely unchallenged, with even the heaviest settings leaving significant performance in reserve.

Moving to 2560x1440, the performance remains exceptionally high, though the increased pixel count begins to exert a measurable influence. Low settings produce an average of 193.7 FPS, while Medium settings follow closely at 168.6 FPS. High settings deliver 140.9 average FPS, and Ultra settings maintain a strong 114.7 average FPS. The scaling between presets is consistent, with each step up in quality costing roughly 20-30 FPS at this resolution. The gap between Low and Ultra at 1440p is 79 FPS, which illustrates the substantial impact of the settings menu on overall performance.

At 3840x2160, the RTX 3080’s memory bandwidth and compute resources are more fully utilized, yet the combo still clears the 60 FPS threshold with room to spare. Low settings average 106.5 FPS, providing a very playable 4K experience. Medium settings average 93.9 FPS, while High settings average 78.7 FPS. The Ultra preset, which represents the maximum visual fidelity, averages 62.5 FPS. This is the only configuration where the average dips close to the 60 FPS line, but it stays above it, confirming that even the most demanding 4K settings are playable. The progression from Low to Ultra at 4K shows a drop of 44 FPS, which is proportionally similar to the drop seen at 1440p.

The absence of min and max FPS values in the data means the analysis relies on averages, but the consistency of the scaling across all three resolutions suggests a well-balanced system. The frame rate deltas between presets are smooth, with no anomalous jumps that would indicate a bottleneck or driver issue. For example, at 1080p, the difference between Low and Medium is 44.1 FPS, between Medium and High is 39.1 FPS, and between High and Ultra is 40.9 FPS. This nearly uniform step-down indicates predictable performance scaling.

CPU and GPU Roles

The division of labor between the Intel Core i5-14600K and the NVIDIA GeForce RTX 3080 becomes clearer when examining how performance scales with resolution and settings. At 1920x1080, the frame rates are extraordinarily high, which suggests that the CPU is playing a significant role in keeping the GPU fed. The 14600K, with its 14 cores and 20 threads, provides ample processing power to drive the high draw-call rates and game logic that Doom’s engine requires at such elevated FPS levels. The jump from 220.3 FPS at High to 303.5 FPS at Low indicates that the CPU can handle the lower graphics workload without becoming a limiting factor, as the GPU is given less work to do per frame.

As the resolution increases to 2560x1440, the GPU begins to take on a more dominant role. The average FPS drops from the 300 range at 1080p to the 190 range at 1440p with Low settings, a reduction of 109.8 FPS. This substantial decrease is primarily attributable to the increased pixel count, which places a heavier load on the RTX 3080’s shading units and ROPs. The CPU’s influence diminishes relatively, as the GPU’s rendering time per frame grows. However, the 14600K still ensures that the GPU is never starved for data, as evidenced by the strong performance at 1440p High (140.9 FPS) and Ultra (114.7 FPS).

At 3840x2160, the GPU is unequivocally the primary performance driver. The RTX 3080’s 10 GB of GDDR6X memory and 760.3 GB/s bandwidth are fully engaged, and the frame rates show a clear dependency on the GPU’s compute capabilities. The difference between Low (106.5 FPS) and Ultra (62.5 FPS) at 4K is 44 FPS, which is nearly identical to the 44 FPS delta observed at 1440p. This similarity suggests that the CPU is no longer a factor at 4K, as the GPU’s workload scaling with settings dominates the performance equation. The 14600K’s role at 4K is to maintain a stable baseline, which it does effectively.

The scaling between resolutions further confirms this role split. At Low settings, the frame rate drops from 303.5 at 1080p to 193.7 at 1440p (a 36% reduction) and then to 106.5 at 4K (a further 45% reduction). At Ultra settings, the drop from 1080p (179.4 FPS) to 1440p (114.7 FPS) is also 36%, and the drop to 4K (62.5 FPS) is 45%. This consistent percentage scaling across settings indicates that the GPU’s performance curve is smooth and predictable, with the CPU providing sufficient headroom at all times. The data does not show any scenario where the CPU becomes a bottleneck, as the frame rates scale proportionally with the GPU’s workload.

How This Combo Ranks

The Intel Core i5-14600K and NVIDIA GeForce RTX 3080 combination holds a comboRankInGame of 1089 out of 3712 tested configurations for Doom. This places the system in the upper third of all tested hardware pairings, specifically at the 70.7th percentile. The rank reflects the combination’s ability to deliver high frame rates across all resolutions, but it also shows that there are many faster systems in the database, likely featuring newer or higher-tier GPUs. The rank is impressive given that the RTX 3080 is an end-of-life product, yet it still outperforms the majority of tested setups.

The GPU’s percentileVsAllGpus is 68, meaning it scores higher than 68% of all GPUs in the database, while the CPU’s percentileVsAllCpus is 90, indicating it outperforms 90% of all CPUs. The disparity between these percentiles suggests that the CPU is relatively stronger than the GPU in this pairing. However, for Doom, the GPU-centric workloads at higher resolutions mean the RTX 3080’s absolute performance is the key determinant of the final rank. The combo’s rank of 1089 is consistent with a system that excels at 1080p and 1440p but is merely good at 4K Ultra, where the 62.5 FPS average is close to the playable threshold.

The data shows that the combo’s position is not an outlier; it aligns with the expected performance of a high-end 14th-gen Intel CPU paired with a 30-series GPU. The rank of 1089 indicates that while this is not a top-tier 4K powerhouse, it is a very capable system for competitive and high-refresh-rate play. The lack of min FPS data means that stutter or frame-time consistency cannot be assessed, but the high average scores across all presets suggest a smooth experience in typical gameplay scenarios.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-14600K, based on average benchmark scores, offer insight into what other CPUs would perform similarly in this system. The Intel Xeon Gold 5318H has an average score of 48698, which is 0.2% lower than the 14600K’s average. The AMD EPYC 4345P scores 48470, a 0.3% difference. The Intel Core Ultra 5 245HX and Intel Core Ultra 5 245 are also close, with scores of 48287 and 48995, respectively, representing deltas of 0.7% and -0.8%. These alternatives would likely produce nearly identical frame rates in Doom, as the game is not particularly CPU-bound at higher resolutions, and the 14600K’s lead is marginal.

For the GPU, the nearest rivals to the RTX 3080 are notably lower-tier products, which is a quirk of the average benchmark score comparison.
